We are the first to successfully utilize the INPNC membrane-bound protein to display DARPin H10-2-G3 that retains its picomolar affinity for HER2. As a result of these experiments, we have developed a INPNC surface display vector, which allows for the simple and straightforward display of a wide variety of proteins such as fluorescent proteins (mCherry, antibody mimetic proteins such as DARPin H10-2-G3, and epitope tags such as the Human influenza hemagglutinin (HA) tag.

Furthermore, in an effort to speed progress and information sharing between iGEM teams, government research organizations, and private research groups, we have proposed a system known as VerifiGEM that would allow for the quality control of BioBricks to be distributed across the entire iGEM community. Should our system be implemented, the overall quality and reliability of BioBricks will be improved greatly, at very little cost to individual iGEM teams.

Modular Light Dependent Expression of Cytolysin A

We are the first to utilize the pDawn YF1/FixJ system to express the ClyA hemolysin protein as a drug delivery system. We have shown that the system is capable of responding to blue light stimulus in a relatively short time span, and that the expression is entirely light dependent and is tightly controlled. We have further shown that this module is capable of operation independent of the remainder of the system, and that the pDawn system is capable of operating in non-traditional E. coli. strains such as Nissle 1917.

Modular Surface Display System

We are the first to successfully utilize the INPNC membrane-bound protein to display DARPin H10-2-G3 that retains its picomolar affinity for HER2. As a result of these experiments, we have developed a INPNC surface display vector, which allows for the simple and straightforward display of a wide variety of proteins such as fluorescent proteins (mCherry, antibody mimetic proteins such as DARPin H10-2-G3, and epitope tags such as the Human influenza hemagglutinin (HA) tag.

Perception Barriers to Bacterial Therapeutics

However, the removal of biological barriers to bacterial therapeutics alone is not sufficient to enable bacterial therapeutics to move into the drug development pipeline. Through the course of recent history, many high profile technologies, such as gene therapy or nanotechnology have been met with public skepticism and even fear, as the technologies failed to deliver on earlier promises. This prompted a constriction of available funding and subsequently impeded progress in those fields, an outcome that nanotechnology in particular is only just beginning to recover from.

We propose a model, adapted from Gartner Inc, which proposes that the disconnect between the expectations of the public and the realities of scientific research produces an initial "peak of inflated expectations" (and funding), that rapidly disappears as promised advances are delayed or do not work as planned (Figure 1). We believe that this "trough of disillusionment" is the cause of restrictions in funding and a general stall of scientific progress in a given field. We propose that the peak can be smoothed out, reducing the size of peak, but more importantly, eliminating the trough of disillusionment (Figure 2).

Figure 2: The modulation of the extremes of the hype cycle through public outreach efforts such as iGEM.

What then, must we as synthetic biologists do to prevent this fate from befalling our own field of study? Certainly, scientists must perform a balancing act between reporting the advances they have made and making realistic conclusions. iGEM teams in particular have a unique opportunity to impact this cycle. Each time a team teaches a class to younger students, presents their research, or even sets up a fun experiment at a local science event, they are given an opportunity to communicate the potential and the limitations of synthetic biology. This is an opportunity many researchers do not have, and should be treated as more than simply a time to take pictures and have fun (although those are certainly important parts of these events nevertheless).
